FUNCTIONAL OVERVIEW

HDMI RECEIVER

The ADV7622 front end incorporates a 4:1 multiplexed HDMI

receiver boasting support for HDMI features including 3D TV,

content type bits, and advanced features, such as capability discovery

and control. Building on the feature set of existing Analog Devices

HDMI devices, the ADV7622 also offers support for all HDTV

formats up to 36-bit, 1080p Deep Color and all display resolutions

up to UXGA (1600 × 1200 at 60 Hz).

With the inclusion of HDCP 1.4, displays can receive encrypted

video content. The HDMI interface of the ADV7622 allows for

authentication of a video receiver, decryption of encoded data

at the receiver, and renewability of that authentication during

transmission as specified by the HDCP 1.4 protocol. Repeater

support is also offered by the ADV7622.

The HDMI receiver offers advanced audio functionality. It supports

a 6-DSD channel interface with each channel carrying an over-

sampled 1-bit representation of the audio signal as delivered on

SACD. The ADV7622 can also receive HBR audio packet streams

and output them through the HBR interface in an S/PDIF format

conforming to the IEC 60958 standard. S/PDIF is supported via

the HPD back channel. The receiver also contains an audio mute

controller, which can detect a variety of conditions that may

result in audible extraneous noise in the audio output. On

detection of these conditions, the audio data can be ramped

to prevent audio clicks or pops.

The ADV7622 HDMI receiver incorporates active, programmable

equalization of the HDMI data signals that compensates for

the high frequency losses inherent in HDMI and DVI cabling,

especially at longer lengths and higher frequencies. The receiver

also contains a programmable data island packet interrupt

generator.

HDMI TRANSMITTER

The ADV7622 features a single HDMI transmitter supporting

ARC, 3D TV formats as well as all HDTV formats up to 1080p,

36-bit Deep Color.

Supporting both single-ended and differential modes, the ARC

feature simplifies cabling by combining an upstream audio capability

in a conventional HDMI cable.
